Marijuana activist Dana Larsen is making another tour stop in Calgary a year after he was arrested for giving away cannabis seeds.

The Vancouver-based cannabis legalization advocate admits he is “a little nervous” about coming back to the city where he was charged with one count of trafficking marijuana and one count of possession for the purpose of trafficking.

“This year I’m doing 23 cities and Calgary is actually the last stop, and so far no other police force has bothered showing up or interfering with my seed giveaway, so I will be surprised if the Calgary police show up again, but I was surprised they showed up the first time,” Larsen said.

While police are aware of Friday’s event, the Calgary Police Service said in a statement that by standard practice, it does not disclose investigative tactics or operational plans, nor does it disclose information about specific individuals.

Larsen will be in Calgary as part of a cross-country tour he launched in March dubbed the Overgrow Canada Tour. In each city, the activist has given talks on “the hidden history of cannabis in Canada” and given away seeds.

On April 6, 2016, Larsen was arrested at the Days Inn on Macleod Trail South and spent the night in custody before being released on bail.

He will return to Calgary next month for a preliminary hearing on the charges on May 9 and 10. If there is a trial next year, he will be back to attend it, but he said he is doubtful the charges will go to trial.
